Description Sebastian Schneider CLA 2010-05-03 14:53:32 EDT 
Build Identifier: I20100429-2000 / table combo 1.0.0.HEAD

Since TableComboViewer is an AbstractTreeViewer, I utilized the 
ViewerSupport.bind() method for databinding with model.
Actually it's working out find, but when the parent Control is getting disposed (e.g. a Dialog) an Exception is thrown:

It's caused when the methods setSelection() / doGetSelection() get invoked. 

Currently, it seem's to be working fine, when the customized 
handleLabelProviderChanged(LabelProviderChangedEvent event); is removed and the
setSelection(getSelection()) ist not executed.




Reproducible: Always

Steps to Reproduce:
TableComboViewer comboField;
ViewerSupport.bind(comboField, WRITABLELIST,
				BeanProperties.values(new String[] { "property" }));
